Abstract (en)
[origin: EP0621536A1] This debugger (KD) for an operating system of a machine which comprises, among other things, at least one processor (P), in conjunction with the processor a memory (M) and a memory management unit (MMU), is installed in an area of the memory (M) where the virtual addressing mode is equal to the physical addressing mode. Throughout debugging and in accordance with a predetermined procedure, it executes every operation in physical mode and independently of the management unit (MMU). In order to monitor the initialisation phases of the machine, it supports at least two exception vectors (BP, DSI) and comprises, among other things, its own stack (S), a decoder (DEC) using an algorithm which can be operated whatever the context of the analysed process and means (CMM) for storage of the decoded context. <IMAGE>
